Study Objective No prior study has directly compared satisfaction with Depo-Provera to the Mirena intra-uterine device (IUD) among post-partum parous adolescents. Our aim was to make this comparison among post-partum adolescents at 3, 6, and 12 months of follow-up. Participants Post-partum/parous adolescents (aged 20 and younger) choosing either Depo-Provera or the Mirena IUD as their method of contraception. Design Prospective longitudinal survey. Setting The adolescent clinic at the Truman Medical Center, Kansas City Missouri. Main Outcome Measure Satisfaction with and intention to continue the chosen method at 3, 6, and 12 months of follow-up. Interventions None. Results Sixty-six post-partum/parous adolescents were recruited, 37 choosing the Mirena IUD and 29 choosing Depo-Provera for contraception. The 2 groups had similar baseline characteristics. There was no statistically significant difference in overall satisfaction with Depo-Provera versus the Mirena IUD at 3, 6, or 12 months of follow-up. For both contraceptive methods, unpredictable bleeding was most unacceptable at 6 months of follow-up but the trend was only statistically significant for Depo-Provera. For Depo-Provera, there was a significantly lower proportion of participants actually continuing the method at 12 months (42.9%) relative to the proportion who at 6 months had expressed an intention to continue (80.0%; P = .01). This trend was not seen for the Mirena IUD. Conclusion Among post-partum/parous adolescents, overall subjective satisfaction with Depo-Provera and the Mirena IUD is similarly high over 12 months of follow-up. With Depo-Provera, however, there appears to be a disconnect between intention to continue at 6 months and actual continuation at 12 months.
